2. In combination, a rigid heating Vessel having a thin metallic heat conducting bottom provided with the usual opening at the top thereof, a lid or cover conformed and adapted to close said opening, an inclosed electric heater of spiral conformation secured to and spaced from said lid or cover, and insulated electric conductors inclosed in said securing and supporting means, said heater having each convolution oi said spiral disposed in close proximity and presented edgewise to the bottom' ot` said vessel when the lid or cover is in position, and removable t'rom the vessel with said lid or cover, .substantially as described.

3. ln combination, a heating vessel provided with the usual opening at. the top thereot', a lid or cover coniormed and adapted to close said opening, tubes secured to said top, an electric heater of spiral conformation secured to and spaced from said lid or cover by means otl said tubes. said heater being disposed in close proximity to the bottom ol said vessel when the lid or cover is in position and removable from the vessel with .said lid or cover.I a handle for y said cover, a socket in said handle and conductors located in said tubes'electrically connecting said heater with said socket,sub stantiallv as described.

Jr. ln con'ibination, a rigid heating vessel provided with the usual opening at the-top thercot a lid or cover conformed and adapted to close said opening, an inclosed eleetric hcatr spaced and suspended from said lid or cover, and adapted to be completely submerged in the liquid in said vessel,means tor (connecting said heater with a source of electric ener-gv, said heater being removable from' said vessel with said lid or cover, said lid or cover having an opening whereby the interior of said vessel may have communisulated electric heater elcmentrigidly connected to said top and held in proximity to the bottom ot' said vessel, and lead wires insulated from each other and from the heating vessel connected to said heating element and to the socket in said handle whereby said heater, top, and handle form a single unitary structure.

t3. In a heater t'or liquids, a vessel having an open top, a combination for a resistor formed into a fiat spiral body, said resist-or having its edges disposed in a vertical direction to otter a minimum resistance to the circulation oi the liquid, said resistor being inclosed in a metallic sheath metal tubes joining said sheath, lead-wires connecting said resistor disposed in said tubes and means joining the tops ot' said tubes, said means forming a support for said heater and a closure for the top o1" said vessel, said heater being suspended by said support at the bottom of said vessel in a liquid to heat the same.

7. in combination a tea kettle having an open top, a lid for the saine, a handle secured to said lid, circuit terminals in said handle, a pair ol hollow rods secured to the bottom of said lid. a flat resistance heater Jformed into a spiral having the edges presented to the bottom ot' the kettle, a sheath t'or said resistance heater, said sheatlrbcing joined to the hollow rods to constitute a continuous sheath or armor and conductors connecting said resistance and said 'terminals, said conductors passing through said hollow rods.

In witness whereof, l hereunto subscribe my name this 8 day ot' April, A. D., i913.
